NVD Description

Note: Versions mentioned in the description apply only to the upstream airflow-3 package and not the airflow-3 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Ray prior to 2.56.0 contains an unsafe deserialization vulnerability in the WebDataset reader that allows attackers to achieve remote code execution by supplying a malicious tar archive to the read_webdataset() function. The _default_decoder() function in webdataset_datasource.py unconditionally calls pickle.loads() on tar entries with .pkl/.pickle extensions and torch.load() with weights_only=False on .pt/.pth entries, executing arbitrary code inside Ray remote workers on every worker that processes the malicious archive.
